Firstly, support what anshuman84 said above.
Then, I think, the kernel debugger is necessary, such as KGDB (also need GDB in user mode on remote machine) or KDB (can debug in one machine).
KGDB is integrated into kernel in later version (but maybe not in 2.6.27), and KDB is later than KGDB for being integrated into kernel.

And by the way (maybe not quite relative with this issue)
Reading source code and programming carefully (especially for the relative changes) is still a way for solving this issue, it is the sugestion of Linus Torvalds.
Linus does not suggest using debugger: reading source code and carefully programming are much important than debugging (it is truly reasonable)
